CPU temperature higher after restart

[Nick.Petaccio]

Hi, I just put together my first build and have had some trouble with the CPU temperatures. I have an i7 4790k, an Asus z97 pro wifi, and I'm using a NZXT Kraken x61.  Yesterday I ran prime 95 small FFT s and my temps were hitting 80C so i stopped, As soon as i had the chance I cleaned all of the thermal paste off the cooler and the cpu, and put on less then I had before and saw my temps go down t 60-65 under the same test.Then I turned off my computer and brought it home (I built it at work)and when i startedit up myprime 95 temps are back to 80C.  Any one know what's happening and what I can do to fix it.

 

Thanks

my idle temps were 29 this morning and now they are 34 if that helps

I'm assuming you haven't overclocked? How did you apply the thermal paste?

[Enderman]

What is your pump and fan RPMs?

What thermal paste did you use?

Did you mount the backplate correctly so that everything is extremely tight?

[Nick.Petaccio]

No I haven't overclocked and i Put adrop the size of about a pee, first time I did a little more, most recently i did a tad smaller  Im using artic silver paste, and all the screws areas tight. pum rpm is 3720 and fans are at 1920

Hello and welcome to the LTT forums.

 

I would suggest you apply a bit more thermal paste and check to make sure the cooler making good contact with the CPU

 

Hope this helps

It needs to be about the size of a grain of rice. Also what kind of thermal compound are you using?

[Nick.Petaccio]

arctic silver

is there any reason why It handeled 30+ miniutes of prime 95 at 60-65 andnow its at 80 in three seconds

this may seem stupid, but is there any temperature difference between the 2 places you mentioned? 2ºC of change in ambient temperatute may mean worst performance. 

Also, is the case clearance ideal in both cases? I mean, in 1 place you had it on a table while on the other you have it in a furry carpet that block intakes, or is the back exhaust blocked by a wall or something like that?

that was my first thought as well, my house is actually colder then my office and it has only been on flat wood surfaces
